  • Page 11: Using The Hardware

    swru138 Using the hardware The hardware in the kit can be used in two different modes. Either connect the CC2520EM directly to the SmartRF05EB (Figure 7) or connect the EM to the CCMSP-EM and then connect this assembly to the EB (Figure 8). Figure 7 - CC2520EM and SmartRF05EB The first option (Figure 7) should be used when the RF Module is controlled by SmartRF Studio via the USB controller on SmartRF05EB.
  • Page 12 swru138 Figure 9 - EM and MCU board operating standalone Note that it is possible to operate the CC2520EM + CCMSP-EM standalone (i.e. without the EB), but this requires some sort of external power. Figure 9 shows the CC2520EM connected to the MCU board as a standalone unit.
